Add 4
.. 5e^(2x) = 15
Divide by 5
.. e^(2x) = 3
Take the natural log
.. 2x = ln(3)
Divide by 2
.. x = ln(3)/2 . . . . . . . . . corresponds to the 3rd selection
Answer:6

I would say C because D has multiplication instead of adding in the parenthesis and I don't think that is the "basic" way
Answer:
52.5
Step-by-step explanation:
Since this is an isosceles triangle, the base angles are the same
The three angles add to 180
R+ T + S = 180
3x+30 + 3x+30 + 12x-15 = 180
Combine like terms
18x +45 = 180
Subtract 45 from each side
18x+45 - 45 = 180-45
18x =135
Divide each side by 18
18x/18 = 135/18
x = 7.5
We want angle R
R = 3x+30
= 3( 7.5) +30
22.5 +30
52.5
